POCKET WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No 498,868, dated .T une 6,1893.

` Application led September 13, 1892. Serial No. 445,786. (No model.)

To a/ZZ whom t may concern:

Be it known that I, CHARLES LEWIS WA- GANDT, a citizen of the UnitedStates, residing at Baltimore city, in the State of Maryland, haveinvented certain new and useful Improvements in Pocket Window-Screens;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention has for its object to provide a very light and portablescreen adapted to be carried bythe traveler in his pocket or satchel andto be applied at will to any ordinary window for protection againstdust, cinders, or insects.

I have designed my screen especially for car windows, and by its use thetraveler may enjoyl the refreshing breeze ordinarily produced by themotion of the railway train Withont being subjected to the usualaccompanying annoyance of dust and cinders and without being obliged tocarry with him a large or cumbersome article.

lVith these ends in view my invention consists in the parts landcombinations thereof hereinafter more particularly set forth andclaimed.

In order to make the improvement more clearly understood I have shown inthe accompanying drawings means for carrying the same into practicaleffect, without however limiting the invention in its usefulapplications to the particular construction which, for the sake ofillustration, I have delineated.

In said drawings-Figure l is aview of the screen folded and ready fortransportation in the pocket or valise. Fig. 2 is a view of the samepartly unfolded. Fig. 3 is a View of the screen still farther unfolded.Fig. 4 shows the screen extended and made of a length suitable for thewidth of the window to which it is to be applied. Fig. 5 shows thedevice entirely unfolded and applied to the window in the usual manner.Fig. 6 is a sectional View on line VI-VI, Fig. 5. Fig.'7 isa similarview on a larger scale of the top pieces. Fig. S is a similar view of apiece of the screen frame when made of wood.

Referring to the drawings-l and 2 indicate the two top pieces of thescreen frame, and 3 and 4 the bottom pieces of similar shape andconstruction. I may here state that the niateral of the frame may be ofwood or of sheet metal. In the drawingsit is shown as formed of tin. Thesaid top and bottom pieces are provided with inwardly extending ears 5by which they are pivoted together on axes transverse to the plane ofthe screen, the pivot of the top pieces being shown at 6 and that of thebottom pieces at 7.

p S indicates the side or vertical bars of the frame, each formed of twosections 9, 9 pivoted together at l0 on axes which are parallel with theplane of the screen and (when the screen is in position for use) arehorizontal. In other words the pivots l0 are parallel with the top andbottom pieces of the screen when unfolded. The vside sections arepivoted upon the ends of the top and bottom pieces by pins or hinges Ilwhich are at right angles to the pivots l0 and parallel with the pivots6 and 7.

On the pivots I0 the frame may be folded on a horizontal middle line soas to bring the side sections face to face and the bottom pieces againstthe top pieces; on the pivots ll the doubled frame may be foldededgewise to bring the inner edges of the side sections against the inneredges of the top and bottom sections; and on the pivots G and 7 thequadruple folded frame may be still farther folded to bring the outeredges of the side sections against each other.

At one or both sides of the screen I provide an extension so that thescreen may be made of various widths to it different windows. This Ieffect by making the top and bottom pieces 2 and fi in two parts theouter (toward the edge of the screen) parts 11a having a slidingmovement upon the inner (toward the middle of the screen) parts 12. Inthe construction illustrated the parts 12 are hollow in the form ofsheaths and the parts l1 telescope entirely within them. ticulatedmaterial is attached to the frame in any suitable manner. It is made intwo separate parts 13, 14 the former constituting the main portion ofthe screen and the latter being carried by the sliding extension. TheseThe re- 95 two parts are made to overlap each other a sufficientdistance when the screen is fully extended, and by placing the outermostpart toward the forward end of the train the breeze will simply tend tokeep the two parts closely together and dust and cinders will beperfectly excluded.

For the reticulated material a very fine and flexible fabric isemployed. I prefer a rather heavy quality of veiling.

In the construction shown the frame pieces are provided with bends 15 inwhich I crimp and clamp at the time they are formed the edge of a strongcotton or other fabric 16 which extends all around the interior edge ofthe frame. This fabric is made in a narrow strip or strips, to which thereticulated material is sewed to complete the screen. If the frame is ofWood the strip 16 may be secured in a groove by a wedge-strip 1'7, asseen in Fig. 8.

The screen is ordinarily kept in the form shown in Fig. 1. Vhen it isdesired to use it the partly surrounding fabric is unwrapped and theframe unfolded into the position shown in Fig. 2, and then into thatindicated in Fig. 3. While in this position the extension parts of boththe top and bottom of the frame are slid out together so as to nearlyiill the window to which the device is to be applied (Fig. 4), and thenthe lower half of the screen is folded down as seen in Fig. 5. Thedevice is then placed in the window frame between the strips forming thegroove in which the window runs and the extension pieces still fartherslid out until both sides of the screen frame are confined in the saidgrooves. The window sash 2O is then let down on top of the device. Thejoints at 6 and 7 are formed with abutting shoulders 18 which preventthe top and bottom parts of the frame from turning inward toward thecenter of the screen from gravity or from the pull of the fabric, andthe window sash strips, shown at 19 in Fig. 6, so engage the side piecesas to prevent the frame from buckling on the joints at 10. The frame istherefore perfectly rigid while in use. The reverse of the unfoldingprocess above described enables the screen to be returned to the pocket.5

1. The herein described folding pocket window screen, having areticulated material adapted to be Wrapped up without injury, and

a frame composed of top, bottom and side 51 pieces hinged to each other,each of said side pieces being composed of sections hinged together uponpivots the axes of which are transverse to the axes of the pivots bywhich the side pieces are jointed to the top and bot- 6 tom pieces,substantially as set forth.

2. The combination with the main frame portion composed of sectionshinged together at the corners and intermediately between the cornersand adapted to be folded, of an exten- 6 sion frame portion Acomposed ofcorrespondingly hinged sections jointed at the corners and intermedatelybetween the corners and having a sliding engagement with said mainportion, the Whole constituting when provided 7.

the plane of the screen and hinged to said top 8 and bottom pieces,substantially as set forth.

4. In a screen the frame composed of the top and bottom pieces havingsections hinged together by pivots 6, 7 and the side pieces alsocomposed of sections hinged together by piv- 81 ots 10 and at one sideof the screen hinged to the top and bottom pieces by pivots 11, and atthe other side of the frame having both a pivotal and a slidingconnection with the top and bottom pieces, substantially as set forth. 9

In testimony whereof I affix my signature in the presence of twowitnesses.
